Question about Deepcool CG530 4F

I have been buying from Digitec for over 20 years and have always been very satisfied. but with the case?! something like this has never happened to me. I have been waiting for my case for weeks, but new purchase is labelled with 2 days delivery time. when I bought my Deepcool CG530 4F it said 1 week. but after purchase I received a delay email.
